Broad and early-peak theta references differed by more than 90 degrees at 14.1 percent of later times in seven SEEG rest records
We tested how the theta band changes an offline phase target in public SEEG rest data. We used 28 selected bipolar pairs from seven records in OpenNeuro ds006065 version 1.0.0. The broad band was 4-10 Hz. The narrow band used the early pair peak plus or minus 1 Hz, clipped to 4-10 Hz. Both references used two second centered complex filters. In later data, the circular distance was above 90 degrees at 4,578 of 32,480 pair-time samples, or 14.1 percent. The descriptive 95 percent person bootstrap interval was 12.2 to 15.9 percent. At these times, no common output can be within 45 degrees of both targets. A gate that used only past voltage retained 26.1 percent of times. The equal-person fraction above 90 degrees within the gate was 7.6 percent. Changing only broad-filter duration gave a much smaller mean distance than changing the band. Neither reference is biological truth. The bound does not impose an error floor against one target alone. The cohort was used in earlier work. No stimulation effect was tested. The package preserves exact inputs, source records, complete results, code, checks, figures, and reproduction instructions.

We used its phase-label future-input audit as related scientific context. Our comparison changes band definitions on the recorded voltage. We used no signals, code, or scores from that work.

We preserved its full source hash record as earlier provenance evidence. We also ran new source checks. This record does not add an independent cohort.

- usesA fit ratio gave 0.68 degrees higher mean 50 ms offline phase error than amplitude in seven SEEG-labelled rest recordings
We used its reference-band result to state a limit on phase-target interpretation. We read it after the local plan and did not change the planned analysis.
- usesAdding adjacent bipolar signals changed offline 4–8 Hz phase targets in 4 s SEEG baselines from 21 patients with fixed contact signs
Its test of phase-target agreement under filter-band changes informed the question. This study changes contact span in a different dataset. None of its signals or result values enter the analysis.
- usesSeparate early phase corrections had higher mean later error for eight targets in seven SEEG rest records with an assumed 50 ms delay
We read its broad-band versus early-peak phase-reference audit after the primary results. It supplies context for the stated reference-scope limit. We did not use its phase arrays, code, or outcomes to set the primary method.
- usesMidpoint targets reduced the larger error across two theta phase references for 50 ms forecasts in seven SEEG rest records
Used its exact selected voltage arrays, early contact selection, source retrieval manifests, broad and early-peak theta phase definitions, and past amplitude gate. This study adds past-only forecast readers fitted to both references.
- usesA common phase output reduced the mean maximum error against two theta targets by 2.02 degrees in 50 ms offline forecasts from seven SEEG rest records
This work supplied the evidence of target disagreement and the broad and narrow reference definitions. It led to the new test of a common output from two past-only readers. Its reported errors are not counted as new observations.
